Description

[Detailed Description of the Invention] This invention relates to a rain cover structure for an opening/closing window that utilizes the principle of equal pressure, and in particular, is formed simultaneously from the lower frame part and the vertical frame part, and over four circumferences within the frame. This is an improvement that allows outside air to be introduced into the space and instantly responds to changes in outside pressure to maintain an equal pressure state, thereby preventing rainwater from entering due to pressure differences. be.

Conventionally, this type of rain protection method includes, as shown in Fig. 1, a space c formed between a window frame a and a shoji stile b, and an outside air inlet d provided in the window frame a.
Either, as shown in Fig. 2, a gap d' may be provided between the window frame a and the shoji stile b to connect the space c to the outside air. There was a way to equalize the pressure. In these conventional rain cover structures, in order to prevent rainwater from entering the space c due to wind pressure, air currents, etc., a full f is used (see Figure 1), or a gap d' is made into a labyrinth. (See Figure 2). However, these conventional methods cannot completely prevent rainwater from entering, and as a result, rainwater adheres to the airtight material, that is, the tight material e, provided on the indoor side of space c, and due to capillary action, pressure difference, etc. This caused water to leak into the room.

This invention was made in view of the above circumstances,
Inside the space formed around the four circumferences between the shoji stile and the window frame, the bottom frame and vertical frame are clearly defined, allowing outside air to be introduced at the same time, instantly making this space equal to the pressure of the outside air. The purpose is to

Embodiments of the invention will now be described in detail with reference to the accompanying drawings.

Among these drawings, FIGS. 3 and 4 show an embodiment in which the present invention is applied to a rotating window in a curtain wall, and 1 is an upper frame, 2 is a lower frame, and 3 is a vertical frame. A shoji B is fitted into a window frame A composed of frames 1, 2, and 3, and each shoji B is composed of an upper stile 4, a lower stile 5, and a vertical stile 6. Each stile 4, 5, 6 of shoji B and each frame 1, 2, 3 of window frame A
A first space 8 is formed around the four circumferences by providing airtight materials 7, 7' on the indoor and outdoor sides of the gap formed between the two.

On the other hand, the upper frame 1 and the lower frame 2 each have an outer frame portion 1a, 2a and an inner frame portion 1b, which form an eyeless structure.
2b, and these outer frame parts 1
A, 2a and inner frame parts 1b, 2b form a second space 9
is formed. Further, the left and right vertical frames 3 are composed of an outer frame part 3a and an inner frame part 3b, which are made up of enlarged edges 11 and 12 attached to the mullion 10, and these outer frame parts 3a and inner frame parts 3b are Thus, a second space 9 is formed around the four circumferences.
In addition, the inner frame parts 1b, 2b of each frame 1, 2, 3,
3b is assembled into a square shape in advance, and the outer frame parts 1a, 2
a, 3a, and the joint portion thereof is sealed with, for example, a silicone sealing material 13,
In addition, each inner frame portion 1b, 2b, 3b and outer frame portion 1
a, 2a, and 3a are fixed with screws 14, ridges 15, beads 15', or the like.

In this invention, in order to make the first space 8 between the window frame A and the shoji B and the second space 9 in each frame 1, 2, and 3, which are formed as described above, equal pressure with the outside air. In addition, the lower frame 2 and the vertical frame 3 are each equipped with an outside air intake mechanism. In this case, although only one of the left and right vertical frames is shown in the drawings, the outside air intake mechanism may be provided on at least one of the vertical frames. That is, in the vertical frame 3, outside air introduction 16a,
16b and 16c are provided to communicate the second space 9 with the outdoors, and a vent 17 is provided in the inner frame portion 3b to communicate the second space 9 with the outside.
The space 8 and the second space are communicated with each other so that outside air can be introduced into the first and second spaces 8 and 9. In this case, the outside air inlet 16a,
16b, 16c and the vent 17 are provided at positions where adjacent ones are shifted from each other so that the outside air does not pass directly through the outside air inlet 16.
In the vicinity of a, 16b, 16c and the vent 17, drainage ridges 18, 18, . . . are provided to prevent rainwater from entering the spaces 8, 9. on the other hand,
In the lower frame 2, outside air inlet ports 19a and 19b are cut out in the outer frame portion 2a to communicate the second space 9 with the outside, and a vent 20 is provided in the inner frame portion 2b to connect the first space and the first space. The two spaces 9 are in communication with each other, and outside air is introduced into the first space 8 and the second space 9. In this case, the outside air introduction ports 19a and 19b also serve as drainage ports. If,
Needless to say, if it is necessary to provide the outside air inlet at a different location, a drain port is provided separately from the outside air inlet. 21 is a drainage port provided in the lower stile 5 of the shoji screen.

By providing the outside air intake mechanism in this way, rainwater droplets in the vertical frame 3 are removed from the second space 9.
Even if the droplets enter the first space 8, they flow into the second space 9 of the lower frame 2 due to the action of gravity and pass through the outside air inlets and drains 19a and 19b. is discharged outside. It should be noted that rainwater that has entered the outdoor tight material 7' placed between the window frame A and the shoji B for some reason other than the pressure difference, for example due to capillary phenomenon, may enter the first space 8.
The water passes through the second space 9 and is drained to the outside through outside air introduction ports 19a and 19b which also serve as drainage ports. In addition, even if rainwater enters the glass groove C due to capillary action between the watertight material 23 provided on the outdoor side of the glass 24, the glass, and the stile, rainwater will flow through the drain port 21 provided at the bottom of the glass groove C. 1st of 2
It passes through the space 8 and the second space 9 and is discharged outside.

As explained above, the rain closing structure of the present invention is constructed by cutting off the indoor and outdoor sides of the gap formed between the shoji stile and the window frame with an airtight material to create a first space around the four circumferences. In addition to forming
The window frame has a double structure with an inner frame part and an outer frame part having a second space extending all around, and furthermore, the second space and the outdoors are communicated through the outside air inlet, and the first space and the second space are communicated with each other through the outside air intake. The second space is communicated with the outside air through a hole, and the pressure between the first space and the second space is equal to the outside air. In order to maintain equal pressure, all rainwater droplets that enter from outside through the outside air inlet are treated in the second space, and outside air that does not contain rainwater can be taken into the first space. ,
A complete rain cover can be performed. Furthermore, since outside air is simultaneously introduced through the outside air introduction holes formed in both the vertical frame and the lower frame of the outer frame, the pressure within the first and second spaces communicating with the four circumferences is instantly equalized, thereby reducing the outside pressure. can respond to fluctuations in
It becomes possible to completely prevent rainwater from entering due to pressure differences. Further, according to the present invention, outside air is introduced from a slit-shaped opening between the shoji stile and the window frame, as in conventionally used windows that can be opened and closed by tilting outward, tilting inward, sliding out, etc. Even if the type is an open/close type, double tight material can be installed indoors and outdoors, so you can take advantage of this double tight method and combine this tight material with the equal pressure method. It is possible to perform extremely safe rain closure, and according to this invention, watertightness can be maintained even during high wind pressure, so it can be applied to opening/closing windows, which were conventionally said to be unsuitable for skyscrapers. It can have a great effect on the building environment and, for example, natural ventilation during the mid-season period. In addition, since the window frame in this invention is composed of an inner frame part and an outer frame part, its shape and the position of the cutout of the outside air inlet can be freely designed.
It has excellent effects such as being easy to manufacture.
